摘要
目的 :对高危人群的乳腺进行广泛普查 ,旨在研究不同时期正常乳腺的高频超声特征及彩色多普勒血流参数 ,以便与乳腺疾病进行对照 ,找出区分正常与疾病之间 ,良性与恶性病变之间规律性的参数 ,以期达到筛选早期乳癌的目的。方法 :用彩色超声诊断仪 ,对 2 0～ 70岁妇女的乳腺进行区域性普查。结果 :普查 3万人 ,筛选阳性病例 85 80人(15 1% ) ,其中乳腺癌 32人 (0 .1% )。结论 :利用脉冲多普勒 (PW)所测的Vp =2 2± 1.2cm/s,PI =1.4 9± 0 .2 0 ,RI =0 .82±0 .0 7作为区分良、恶性病变之间的临界值 ,可明显提高筛选早期乳癌的敏感性达 82 % ,特异性达 81%。彩色血流显像(CDFI)信号 0 -Ⅱ级者多数为良性肿块 ,Ⅲ -Ⅳ级者为恶性肿块 ,Ⅳ级是诊断乳癌的一个非常重要的指标。
Objective:To make an extensively general mammary glands of the women in high danger,study the high-frequency ultrasonic characteristics of the normal mammary glands in different periods and the blood-flow parameters of color doppler in order to contrast them with mammary gland diseases,and then find the regular parameters between normal conditions and diseases and between benign tumours and malignant tumours,so as to obtain the purpose of selecting the earlier-period breast cancer.Methods:To make a regionally general survey of the mammary glands of the women with the ages bentween 20 and 70 by color ultrasonic diagnostic apparatus.Results:After 30 thousand women were surveyed, 3580 positive sick cases (15.1%) were selected, including 32 women (0.1%) with mammary gland cancer.Conclusion:Taking such tested values by pulse doppler as the critical values Vp=22±1.2cm/s, PI=1.49±0.20, RI=0.82±0.07 which can obviously raise the susceptibility of selecting earlier-period cancer to 82% and the specificity to 81%..The CDFI signals at 0～Ⅱ levels are mostly benign tumours. The signals at Ⅲ～Ⅳ levels are malignant tumours.The signals at Ⅳ level are the very important index for diagnosing breast cancer.
